Zernio is the marketing infrastructure 200,000 developers build products on. We absorb the integrations, platform approvals and maintenance behind every channel, all on official APIs, so you can start building today. One API covers 16 social platforms, ads on 7 networks, WhatsApp, iMessage, and phone numbers with calls and SMS that you buy inside Zernio. Use the REST API in your code, or let your coding agent do the same through our MCP server and CLI.
Hey everyone! Excited to be back on Product Hunt with Zernio :)
When we first launched here in March, Zernio was a social media API. Developers came to us so they didn’t have to build and maintain an integration for every platform, and social is still the biggest part of what we do.
Then you kept asking for more. Since then we’ve added ads across 7 platforms, WhatsApp, iMessage, and phone numbers with calls and SMS, all on the same API. Today 200,000 developers build on Zernio, and we’re finally ready to grow from a social media API into marketing infrastructure that you and your agents build on.
Connect our MCP server, and your agent can post, run ads, text and call. We have plenty of ideas for what comes next, but we’d love to hear yours.
Use this launch to tell us what you still can’t build on Zernio. Thank you all for the support!
I've been using Zernio for about 2 months, what initially drove me to it was the better value compared to other more popular options (at that time). They ship lots of features really quickly, I'm really happy with it so far, best of luck.
how many tools does the agent see through the MCP with all 16 platforms plus ads and calls? from our experience at ApyHub the tool list gets long fast, that's why our MCP is just 4 generic tools
Huge congrats on the launch!
Would love to try it out. To use Instagram, Facebook does App needs to be created?
Been loving the product for posting to social via agents. I'm sure I'll grow into the rest of the goodies they've been adding too. Keep it up!
Zernio is amazing, we have made it a core part of our offerings to customers. An incredible offering, we leverage the platform to quickly generate MCPs and company brains for our clients.
Keep up the awesome work team, been along for this ride since you were late...incredible evolution. Wishlist item is a way to fully configure ad accounts or manage spend/billing methods via Zernio.
Cracked team that are constantly shipping good stuff! Congrats with the launch guys 🙌
the phone numbers with calls and SMS bought inside Zernio is the part I'd stress test first. we build voice agents at Dial and the actual hard part of telephony was never the API shape, it was the carrier-side stuff - A2P 10DLC registration for SMS, STIR/SHAKEN attestation so your calls don't get flagged as spam, and the week-plus approval lag when a carrier decides your use case looks sketchy. does Zernio absorb that compliance layer too, or is "buy a number inside Zernio" still handing the user a number that can get silently throttled by a carrier for reasons outside your API
Congrats, Miquel and team! Nice to see the extra channels come from what customers were asking for. Keeping the same API as you add them makes sense.
Long time user of the platform here (since it was called "Late"!) and as a Digital Marketer of many, many years I can tell you that this is a superior product, a conscientious (and very clever) team behind it, and they're keeping up with all the needs of a modern Marketer including supporting agents / MCP. I've yet to integrate the platform with our own product(s) but we will as it was always part of the long-term plan so I'm happy to continue supporting this whole mission.
Do you handle US A2P 10DLC registration for the numbers, or is that on the developer? That's usually the slowest part of getting SMS live, and it's where agent-sent texts get filtered without anyone noticing.
Absorbing the platform approvals and maintenance behind every channel is the unglamorous part of marketing infrastructure that teams underestimate until their integrations start breaking, so handling that on official APIs is a real value proposition. One API across 16 social platforms plus ads and messaging is a wide surface. How quickly do you handle it when a platform changes its API?
Zernio is one amazing product that solves a lot of problems for small time developers like us.. Superb support, easy to use features and a really simple pricing model..
Absolutely love it!
Whether you're vibe coding, no coding or just coding Zernio is a massive time saver.
Because everything operates using official APIs, how does rate limiting and account-level permissions operate when I am dealing with a large number of end user accounts? Btw, Congratulations @paletmiki , @dasha_nazarova1 , @pauguirao & team Zernio ✌️
The most cracked team! Real problem, real solution.
Doing social media the old way makes no sense anymore 🔥
I've been using Zernio since July, and the best compliment I can give is that I barely open it.
I work in batches as I'm the product person who sometimes need to jump into marketing: Wrote a week worth of content ideas, hand it to Claude Code, and it schedules everything across platforms through the API. When the agent gets stuck, it asks your MCP docs instead of me (the best support ticket is the one I never see). Posting to every platform by hand used to be a pain of my existence (slightly exaggerated, but only slightly). Now it’s not a task. Not a tab I keep open. Just plumbing that works.
Congrats on the launch!

Who hunted Zernio?
Zernio was hunted by fmerian. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
